Fluoride Application

Fluoride varnish application is part of preventive oral and dental health treatments. Fluoride is a mineral that strengthens tooth enamel and makes it resistant to decay, preventing tooth decay. It is especially recommended for children at high risk of cavities.

How is Fluoride Varnish Applied?

Fluoride application, which should be done every 4-6 months in children, is a simple procedure performed under the supervision of a dentist. Before the application, the teeth should be brushed. After the tooth surface is cleaned of food and plaque residues, fluoride gel or varnish in the form of a preparation is applied to the teeth after they are dried and isolated from saliva. Fluoride varnish, available in single-use packages, is applied by the dentist to the slightly moist tooth surface for 2-4 minutes.

What Should Be Done After Fluoride Varnish Application?

After the application, the patient should avoid certain foods for 1-2 hours. It is advisable to consult your doctor regarding eating and drinking substances. Since it is an application made only to the tooth surfaces, it is performed safely in a clinical setting without any side effects.

What is the Effect of Fluoride on Teeth?

Fluoride contributes to the formation of quality enamel in terms of protection against decay by ensuring healthy development and good mineralization during enamel formation.

Fluoride can easily replace OH-ions in the apatite structure or fill in the missing OH-ions, forming a more resistant structure called fluorapatite. This makes the tooth enamel less soluble in acids.

Fluoride reduces the solubility of enamel and supports remineralization. After the teeth erupt, fluoride acts locally. This effect can be achieved through fluoride toothpaste, fluoride mouth rinses, fluoride gels, and fluoride varnishes.

What is Fluoride Gel?

Fluoride gel is a decay-preventing agent applied to tooth enamel. With the effect of fluoride, tooth enamel becomes more resistant and harder against microorganisms. This results in stronger tooth enamel.

The most commonly used forms of fluoride gel are APF (acidulated phosphate fluoride) and Sodium Fluoride. These gels, available in various flavors for children, provide an extremely comfortable, simple, and painless application.

How is Fluoride Gel Applied?

Fluoride gel is placed in special spoons designed for children and kept in the mouth for 4 minutes. After the procedure, the excess fluoride gel is removed with a saliva absorber, and the child spits out the remaining excess gel. Mouth rinsing, eating, and drinking should be avoided for half an hour. In addition, milk and dairy products should not be consumed until the next morning.

What is Fluoride Varnish?

Agents in the form of resin and ethanol added to lacquer are called “varnish.” Fluoride varnishes are applied to the teeth using special brushes. They are particularly used in children who cannot tolerate fluoride trays due to the gag reflex and in disabled children who require special attention.

How is Fluoride Varnish Applied?

It is applied to the teeth using a special brush. It dries immediately within seconds of contact with saliva. There is no need to spit. It is necessary to avoid eating anything for 2 hours after the application. The longer this period is extended, the more effective and lasting the fluoride’s effect on the tooth enamel. On the day of varnish application, the teeth should not be brushed, but regular brushing should continue the next day.
